+# Go Client for DTM
+
+There are there packages:
+
+## workflow
+Workflow is a new client for DTM. It support the mixed usage of patterns saga, tcc, xa. And it also support the mixed usage of http, grpc and local transactions.
+
+This pattern offers maximum flexibility and can handle a wide range of scenarios. This pattern is highly recommended for transactions that need to be rolled back
+
+Quick start for workflow using http can be found here: [https://github.com/dtm-labs/quick-start-sample/tree/main/workflow-http](https://github.com/dtm-labs/quick-start-sample/tree/main/workflow-http)
+
+Quick start for workflow using grpc can be found here: [https://github.com/dtm-labs/quick-start-sample/tree/main/workflow-grpc](https://github.com/dtm-labs/quick-start-sample/tree/main/workflow-grpc)
+
+Detailed examples can be found here: [https://github.com/dtm-labs/dtm-examples](https://github.com/dtm-labs/dtm-examples)
+
+
+## dtmcli
+dtmcli is the http client for patterns: saga, tcc, msg, xa
